Development of Discovery Learning Student Worksheets to Improve Students' Critical Thinking Skills in Chemical Balance Materials

Abstract

This study aims to determine the quality of Discovery Learning Student Worksheets to improve students' critical thinking skills and increase students' Critical Thinking Skills on chemical equilibrium material. This study uses research development methods with the design of the Borg and Gall models. The samples in this study were 140 students of Al-Falah Islamic Senior High School Aceh Besar to develop Student Worksheets and 61 people of IT Al-Fitiyan Senior High School to implement Discovery Learning Student Worksheets. The instruments used were questions and student response questionnaires. The data analysis technique uses the percentage equation and analysis of students' critical thinking skills improvement using the N-gain equation and independent-sample t-test. The results showed that the quality of the Discovery Learning Student Worksheets could improve students' critical thinking skills on chemical equilibrium material, as evidenced by the results of the quality assessment of the Discovery Learning Student Worksheets from the validation results obtained an average of 79% with a decent category. The analysis of students' critical thinking skills proves that there is a difference in the average critical thinking skills of students before and after applying the Discovery Learning Student Worksheet on chemical equilibrium material with a Sig value. (2-tailed) < 0.05. The results obtained prove that the use of Discovery Learning Student Worksheets is better than conventional Student Worksheets in improving students' Critical Thinking Skills

Influence of the Use of Student Worksheet Problem-Based to Increase Problem Solving Skills and Learning Outcomes

“…learners re-check all the steps that have been done, see the accuracy of the answers and the suitability of the answers to the questions. In accordance with the research obtained, it proves that the use of Discovery Learning student worksheets is better than conventional student worksheets in improving students' Critical Thinking Skills (Rizki, 2021).…”

Development of Electronic Student Worksheets (e-SW) Electrolyte and Nonelectrolyte Solutions based on Project Based Learning (PjBL) on the Learning Outcomes

“…The development of e-SW has been carried out by Adilla, et al, (2018), namely the development of e-SWbased guided inquiry with Flip PDF Professional and 3D Pageflip based on Problem Based Learning (Hidayah et al, 2020). The developed E-SW is able to make students more interesting to learn and able to improve science process skills and students' critical thinking skills (Wazni & Fatmawati, 2022;Rizki, et al, 2021). In addition to innovative teaching materials, educators are required to be able to realize an active and meaningful teaching and learning process through the selection of appropriate and appropriate learning models.…”

Validity and Practicality of Chemical Equilibrium Electronic Student Worksheets Based on Guided Discovery Learning to Increase the Critical Thinking Ability

“…The Student Worksheet also contains a set of basic activities that must be carried out by students to maximize understanding to form basic abilities according to indicators of achievement of learning outcomes taken (Nizar et al, 2016). The development of Student Worksheet is effective for increasing mastery of concepts (Doyan & Rahman, 2021), the learning process runs actively by training students to develop skills and find concepts (Rizki et al, 2021), to increase learning motivation and student learning outcomes (Ichsan, 2021). The learning process using Student Worksheet showed a significant increase in learning outcomes (Asma, 2020), increased knowledge (Ariani & Meutiawati, 2020), and students' skills in solving given problems (Wahyuni et al, 2020).…”
